MicroRNAs (miRNAs) contribute to the pathogenesis of many forms of cancer, including the pediatric cancer neuroblastoma, but the underlying mechanisms leading to altered miRNA expression are often unknown. Here, a novel integrated approach for analyzing DNA methylation coupled with miRNA and mRNA expression data sets identified 67 epigenetically regulated miRNA in neuroblastoma. A large proportion (42%) of these miRNAs was associated with poor patient survival when underexpressed in tumors. More ...[more]

Development and Independent Validation of a Molecular Subtype in High Grade Serous Ovarian Cancer using Formalin Fixed Paraffin Embedded Tissue, Training set

Project description:High Grade Serous Ovarian Cancer (HGSOC) is a histopathological diagnosis and may represent multiple diseases at a molecular level. We investigated whether distinct molecular subgroups may influence treatment choice. The accompanying validation set of data has also been deposited in ArrayExpress under accession number E-MTAB-2570 (http://www.ebi.ac.uk/arrayexpress/experiments/E-MEXP-2570).

Expression data from NcGFP ki/+, NcGFP ki/ki and wt (W4) ES cells

Project description:We generated a gene replacement allele of the E-cadherin locus that express an N-cadherin-GFP fusion in ES cells. Expression profiles of homozygous and heterozygous knock-in ES cells were analyzed in comparison to wt ES cells. The GEO Samples were compared to published data of E-cadherin knock-out ES cells (ArrayExpress, accession number E-MEXP-2836). The comparison data are linked below.

Transcription profiling of Halobacterium salinarum at different time points after cell cycle synchronization to identify cell cycle dependent transcriptome changes

Project description:Cell cycle dependent transcriptome changes of H. salinarum were analyzed using DNA microarrays. Cells were synchronized by a reversible cell cycle arrest caused by addition of the DNA polymerase inhibitor Aphidicolin. Gene expression of the synchronized cells at different time points after Aphidicolin removal was compared to an unsynchronized control culture (treated identically, but without Aphidicolin addition; time points for the control culture pooled).<br><br>Additional processed data is available from the ArrayExpress FTP site in FGEM format: <a href="ftp://ftp.ebi.ac.uk/pub/databases/microarray/data/experiment/MEXP/E-MEXP-1033/E-MEXP-1033.fgem.txt">E-MEXP-1033.fgem.txt</a>

MicroRNA 140-5p is associated with the pathogenesis of multiple sclerosis

Project description:In order to assess potential alterations in microRNA expression in MS patients, we first applied microRNA array to screen the expression profile of 7 controls and 6 patients in the peripheral blood mononuclear cells (PBMC) PBMC when compared to age- and sex-matched controls Peripheral blood mononuclear cells (PBMC) were prepared by density gradient centrifugation using Nycoprep 1.077 medium (Accurate Chemical & Scientific Corp, Westbury, NY, USA). Total RNA including microRNAs were extracted using miRNeasy mini kit (Qiagen, Germantown, MD, USA) and subjected to microRNA high-throughput array with Affymetrix platform. MicroRNA array in Affymetrix 3.0 platform. Quantitative real-time PCR (QPCR) was applied for the validation and amplification of the test samples. Relative fold expression values were calculated based on the expression of Snord96A gene as an endogenous control. Microarray data are available in the ArrayExpress database (HUwww.ebi.ac.uk/arrayexpressUH) under accession number E-MEXP-4673.

Lapatinib and retinoic acid combination treatment of SKBR3 breast cancer cells

Project description:SKBR3 cells, which bear both an HER2 and a RARA gene amplification, were treated for 12 or 48 hours with 100 nM retinoic acid, 100 nM lapatinib or the combination.The two drugs synergize and induce massive apoptosis. The aim is to find the molecular mechanism(s) of this synergism. Gene expression profiling was performed using Agilent two-color 4X44K arrays. Original processed data are available in the archive: http://www.ebi.ac.uk/arrayexpress/files/E-MEXP-3192/E-MEXP-3192.additional.zip
